TO ALL PERSONS TO' WHOM THESE PRESENTS MAY COME:

Be it known that I, NATHAN R. DAvIS, of Freetown, in the county ofBristol, and State of Massachusetts, have invented a new and useful vImprovement in Fire-Arms; and I do hereby declare'the same tobefully described in the following specification, and represented in tbe'accompanying drawings, of which- Figure 1 is a side view of the rear portion 'of a double-barrelled gun, and the front portion of the stock or lock-ease as connected by my invention.

Figure 2 is a side elevation, and i Figure 3 a top view of these parts as they appear when disconnected-from one another.

Figure 4 is a front end view, and y I Figure 5 a vertical section ofthe stock portion and its lock-ease.

In these drawings, A denotes a lock-ease fastened to the rear part of the stock. B B are the barrels,

which are connected together, and in this instance are represented as fastened to another portion, b, of the stock.

from the breeches of the two barrels, each of such tenons being notched on its lower edge in manner as represented at e, and formed with its upper edge arranged at an acute angle with the breech, in manner as shown at f, (see tig. 2.) y

Within the lower part ofthe socket is a tongue, D, which turns on pivots or screws g, extended from the lock-case into the lower parts ofits opposite ends.

The front end of the lock-case has a dove-tailed socket, C, to receive the two tenons oZ 0l, which project When projecting from the socket to its furthest extent, the tongue rests on the inclined lower edge oi part.

i ofthe socket, in manner as shown in iig. 5.

At the middle of its upper edge or part, the tongue has an inclined plane, i, formed on it, in manner as represented in the drawings, the rest of the said upper` edge being rounded to enter the notches of the two tenons d (Z.

A clamp-screw, k, screws vertically into the lock-case, and against the said inclined plane, when the tongue is back or wholly within its chamber or socket.

On placing the tenons on the upper edge ofthe tongue, when the tongue projects from the case, and tipping up the barrels until the upper parts of' the tenons may enter thesocliet of the case, and next crowding together the barrels and ense or stock, the tongue will he caused to fall back-into the socket and force the tenons upward into the same. Next, by turning down the screw upon the inclined plane, the tongue will be fastened in place or be prevented from being moved forward, so as to disconnect the barrels from the stock.

A single barrel, having either one or two tenons projecting from its breech, may be fastened to the' stock by means like or analogous to such as hcreinbci'ore described. The clamp-screw may enter a notch so formed in the 'tongue as to cause thescrew to hold the tongue in its upright position only, but when the inclined plane is used with the tongue, the screw, by acting against such plane, will force the tongue backward so as to cause it to draw the breech ofthe barrels close up to the lock-case.` K f i I I claim the combination and'arrangement of the tongue and clamp-screw with the tenen-socket ofthe stock or its lock-case, such being to operate with the tenen or tenons ofthe barrel or barrels, as specified.

I also claim the combination of the inclined plane with the tongue and the clamp-screw, arranged with respect to and combined with the socket, for receiving the tenen or tenons of the barrel or barrels, as described.
